These plates differ from Dortokidae
because they do not share several characters of their diagnosis (de
Lapparent de Broin et al., 2004) such as the presence of a strong
medial ornamentation of tubercles and pits, crests and ridges at
least on the neural plates, or longitudinal-oblique crests on some
regions of the plastron; the first pleural scute being at least partly
excluded from the second costal plate; and the presence of long
ischiatic scars.
